Awards, Fellowships, and Honors:
• Fellow, American Physical Society (2004). The citation reads, "For seminal contributions of experimental research on basic physical processes important to both laboratory and astrophysical plasmas, including dynamo effects, magnetic reconnection, magnetic helicity conservation, and magnetorotational instability."
• Kaul Prize for Excellence in Plasma Physics Research and Technology Development, Princeton University (2003). The citation reads, “For the thorough experimental investigation of driven magnetic reconnection in a laboratory plasma. In this work, careful diagnostic studies of the current sheet structure and dynamics, ion heating, and associated wave activity have provided a major advance in the understanding of reconnection processes in laboratory and astrophysical plasmas.”
• Award for Excellence in Plasma Physics Research, American Physical Society (2002). The citation reads, "For the experimental investigation of driven magnetic reconnection in a laboratory plasma. In this work, careful diagnostic studies of the current sheet structure, dynamics and associated wave activity provide a comprehensive picture of the reconnection process."
• Outstanding Mentor Award, Department of Energy (2002). The citation reads, “In recognition of your dedication as a mentor, to share knowledge and to inspire and instill confidence in the next generation of scientists and engineers by setting high expectations, seeking creative solutions, and immersing inquisitive minds in the world of science.”
• Kanbayashi International Fellowship, Japan (1986-1990).
• Iwatani Memorial Fellowship, Japan (1985-1986).
